Hi. Perhaps you can include a sample of some code you're using to create the child contact history record related to the parent customer/prospect record?
Have you tried using a variable to hold the unique ID of the contact record and set the contact ID field of the new contact history record with that variable?
I guess the problem was one of timing Cab't link to a record that does not yet exist!
I did as you suggested and it basically works.

This sounds like a classic use for creating related records via a portal. You have to set the relationship definition to allow portal-creation of new records in the child table, but the parent record's ID will be auto entered when working via the portal.
